The ONE Thing by Gary Keller — book cover

The ONE Thing

Gary Keller · 2013

Extraordinary results come from going small, not wide: identify the single most important task that makes everything else easier or unnecessary, then protect time to do it first. This is a practical playbook for trading scattered effort and fake multitasking for one ruthlessly focused priority.

Why it’s on the shelf

A focusing-question framework to identify the single domino that makes everything else easier.

Three of the ideas you’ll keep

The Clif summary of The ONE Thing pulls out 7 insights. Here are the first three.

  1. Ask the Focusing Question every day: "What's the ONE Thing I can do such that by doing it everything else becomes easier or unnecessary?" Anchor it to a timeframe (right now, today, this week, this year) and use it for both your big-picture goal and your very next action.
  2. Reject the lie that everything matters equally. Apply an extreme version of the 80/20 rule to turn a long to-do list into a short 'success list' built around the vital few, until you're left with a single lead task.
  3. Stop multitasking. Switching between tasks bleeds time and accuracy through constant 'switching costs'; give your ONE Thing undivided attention instead.

The other 4 — and the full 11-minute summary — are in the app.
